Description

Die Erfindung betrifft ein elektrisches Heizkissen und besteht darin, daß die beiden Breitseiten der flachen Heizquelle durch zwei als Wärmespeicher dienende Metallplatten von hoher Wärmekapazität unmittelbar eingeschlossen sind, die ihrerseits von einer an sich bekannten, die Wärme schlecht leitenden und das teilweise oder ganz aus dünnem Blech bestehende Gehäuse erfüllenden Masse derart ίο umgeben sind, daß eine Stromzufuhr von nur wenigen Minuten genügt, die Metallplatten stark zu erhitzen. Die Wärme dieser Metallplatten dringt alsdann nur langsam durch die umgebende Füllmasse und mit entsprechend erniedrigter Temperatur nach außen, so> daß sie dem menschlichen Körper erträglich bleibt und lange Zeit vorhält.The invention relates to an electric heating pad and consists in that the two Broad sides of the flat heating source through two metal plates from high heat capacity are directly included, which in turn of a per se known, the heat poorly conductive and partially or entirely made of thin sheet metal existing housing fulfilling mass are so ίο surrounded that a power supply of only A few minutes is enough to heat the metal plates strongly. The heat from these metal plates then penetrates only slowly through the surrounding filling compound and with a correspondingly reduced temperature to the outside, so> that it remains bearable for the human body and lasts for a long time.

Auf der Zeichnung ist beispielsweise eine Ausführungsform eines Heizkissens entspreao chend der Erfindung dargestellt.For example, an embodiment of a heating pad is shown in the drawing accordingly represented the invention.

Abb. ι zeigt einen Schnitt durch das Heizkissen nach der Linie I-I der Abb. 2;Fig. Ι shows a section through the heating pad along the line I-I of Fig. 2;

Abb. 2 ist ein Querschnitt im Grundriß undFig. 2 is a cross-section in plan and

Abb. 3 eine Gesamtansicht des Heizkissens in schaubildlicher Darstellung.Fig. 3 is an overall view of the heating pad in a diagrammatic representation.

Auf der Zeichnung ist mit 1 ein Steckkontakt oder Lampenanschluß bezeichnet, mit 2 ein Zuleitungsdoppelkabel und mit 3 und 4 der Plus- und Minuspol der das Heizkissen bildenden elektrischen Kleinwärmevorrichtung. Im Innern des Heizkissens ist eine flache elektrische Heizbatterie angeordnetj und die beiden Enden des Heizdrahtes dieser Batterie stehen mit dem Plus- und Minuspol 3 und 4 in leitender Verbindung. Zu beiden Seiten der flachen Heizbatterie 5 ausNickelindraht sind zwei als Wärmespeicher dienende Metallplatten 6, 6' angeordnet, die zweckmäßig miteinander verbunden sind. Die beiden Metallplatten 6,6' sind von einer die Wärme schlecht leitenden Masse 7 aus Asbest, Schamotte, Kieselgur u. dgl. umgeben, die ihrerseits in einem Gehäuse 8 untergebracht ist, das ganz oder teilweise aus Metall bestehen kann.In the drawing, 1 denotes a plug contact or lamp connector, with 2 a double supply cable and with 3 and 4 the plus and minus poles of the heating pad forming small electrical heating device. There's one inside the heating pad flat electric heating battery arranged and the two ends of the heating wire of this Batteries are in conductive connection with the plus and minus poles 3 and 4. To both Sides of the flat heating battery 5 made of nickel wire are two serving as heat accumulators Metal plates 6, 6 'arranged, which are expediently connected to one another. The two Metal plates 6,6 'are made of a mass 7 of asbestos, which does not conduct heat well, Fireclay, kieselguhr and the like, which in turn are housed in a housing 8 which can consist entirely or partially of metal.

Bei der Benutzung des Heizkissens wird diesem mittels des Kabels 2 während weniger Minuten elektrischer Strom zugeführt, durch den die Heizbatterie S stark erhitzt wird, worauf das Zuführungskabel entfernt wird und das Heizkissen für lange Zeit gebrauchsfertig ist.When using the heating pad this is by means of the cable 2 for less Minutes electrical current is supplied by which the heating battery S is strongly heated, whereupon the supply cable is removed and the heating pad is ready for use for a long time is.
